RMAN冷拷贝搭建DataGuard物理备库
1.配置主库环境
启用归档
SQL> alter system set log_archive_dest_1='location=/Oracle/archive_log/arch_%t_%s_%r.arc' scope=spfile;
系统已更改。
SQL> ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='arch_%t_%s_%r.arc' scope=spfile;
系统已更改。
SQL> shutdown immediate
数据库已经关闭。
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> startup mount
ORACLE 例程已经启动。

Fixed Size 2757504 bytes
Variable Size 738200704 bytes
Database Buffers 1778384896 bytes
Redo Buffers 19398656 bytes
数据库装载完毕。
SQL> alter database archivelog;
数据库已更改。
SQL> alter database open;
数据库已更改。
SQL> archive log list
数据库日志模式 存档模式
自动存档 启用
存档终点 /oracle/archive_log
最早的联机日志序列 10
下一个存档日志序列 12
当前日志序列 12
SQL> alter database force logging;
数据库已更改。
SQL> select force_logging from v$database;
FORCE_LOGGING
--------------------------------------------------------------------------------
YES
2.配置Oracle Net
主Oracle Net
SQL> !
oracle@Sol_ORA:~$ cd $ORACLE_HOME/network/admin
oracle@Sol_ORA:/oracle/12.1/network/admin$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/12.1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
TESTM = #主库的连接字符串
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.188.1.176)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TESTM)
)
)
LISTENER_TESTM =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.188.1.176)(PORT = 1521))
TESTS = #备库的链接字符串
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.188.3.20)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TESTM)
)
)
oracle@Sol_ORA:/oracle/12.1/network/admin$ cat listener.ora
# listener.ora Network Configuration File: /oracle/12.1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =(SID_LIST=(SID_DESC=(SID_NAME=TESTM)(ORACLE_HOME=/oracle/12.1))) #主库的静态注册
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.188.1.176)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
